NWS Huntsville, AL wrote its last area forecast discussion before the first event at Jul 12, 5:35 PM CST, 2 hours 13 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 635 PM CDT SUN JUL 12 2009 .UPDATE...FOR 00Z TAF ISSUANCE. && .AVIATION...VFR CONDITIONS SHOULD PREVAIL FOR THE NEXT 5-7 HOURS AT BOTH TAF SITES. GIVEN THE RAINFALL AND MOIST AIR MASS IN PLACE...FOG FORMATION IS POSSIBLE...DROPPING VIS TO MVFR BY 04-05Z. TSRA IS POSSIBLE BTWN 10-14Z AS A THUNDERSTORM COMPLEX MOVES SOUTHEAST FROM AR/W TN TO N AL POTENTIALLY DROPPING VIS TO IFR. VIS/CIG SHOULD RETURN TO VFR AT BOTH TAF SITES BTWN 15-16Z BEFORE ANOTHER ROUND OF SHRA/TSRA MOVES OVER REGION BEGINNING 19-20Z DUE TO A SLOW MOVING COLD FRONT. HAVE INCLUDED SHRA ACTIVITY DURING THAT TIME FRAME GIVEN TIMING UNCERTAINTY WITH FRONTAL MOVEMENT. && .DISCUSSION.../ISSUED 240 PM CDT SUN JUL 12 2009/ AFTERNOON CONVECTION HAS DEVELOPED ACROSS THE AREA TODAY AS THE PARADE OF MCS/S AND SHORTWAVES CONTINUES. THE PARADE IS NOT OVER EITHER...AS WE AWAIT THE ARRIVAL OF A STALLED/SLOW-MOVING COLD FRONT THAT STILL HAS A LONG WAY TO GO BEFORE IT GETS HERE. SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)... ALL INDICATIONS ARE THAT WE SHOULD SEE A BREAK IN THE PRECIP THIS EVENING. AS SUCH...I MAY ONLY CARRY LOW CHANCE POPS FOR MOST OF THE EVENING HOURS. HOWEVER...ALL THE MODELS ARE IN AGREEMENT IN SHOWING DEVELOPMENT OF ANOTHER STORM COMPLEX TO THE NORTH/NORTHWEST AND FILTERING THAT INTO THE AREA OVERNIGHT. GIVEN THE STRONG MODEL AGREEMENT AND HIGH POPS GIVEN BY THE MOS...WILL RAISE POPS AFTER MIDNIGHT INTO AT LEAST THE LIKELY RANGE...PERHAPS CATEGORICAL IF A FAVORED AREA CAN BE DISCERNED. VERY HEAVY RAIN WILL BE THE MAIN THREAT OVERNIGHT AS PWATS CROSS ABOVE 2 INCHES...AND PERHAPS GET OVER 2.25 INCHES...WITH THE POTENTIAL FOR MULTIPLE BANDS OF RAIN. CANNOT RULE OUT STRONG/MARGINALLY SEVERE WIND GUSTS EITHER...BUT THIS IS A SECONDARY THREAT. CURRENT INDICATIONS ARE THAT SOME LINGERING PCPN IS EXPECTED ON MONDAY MORNING...WITH PERHAPS A BREAK DURING THE MID-MORNING...THEN REDEVELOPMENT IN THE AFTERNOON. THE AFTERNOON REDEVELOPMENT HOLDS THE GREATEST POTENTIAL FOR SEVERE ACTIVITY...ESPECIALLY IF THERE ARE ANY BREAKS IN THE CLOUDS DURING THE MORNING HOURS TO ALLOW TEMPS TO GET INTO THE UPPER 80S/AROUND 90 AS WE ARE FORECASTING. CAPE VALUES OF 4-6 KJ/KG ARE BEING FORECASTED BY THE MODELS...AND AS SPC NOTED IN THEIR DAY 2 SVR DISCUSSION...SOME OF THE AFTERNOON REDEVELOPMENT COULD CONTAIN DAMAGING WINDS. POPS TOMORROW ARE A LITTLE MISLEADING SINCE THE BETTER RAIN CHANCE IS EARLY IN THE MORNING...BUT SCTD ACTIVITY SHOULD PERSIST OFF AND ON THROUGH MUCH OF THE DAY. THE SFC FRONT SHOULD BE PUSHED DOWN TOWARD THE AREA BY THE CONVECTION ON MONDAY...BUT WHERE IT WILL BE MONDAY NIGHT IS STILL QUITE UNCERTAIN. FOR NOW...WILL HOLD ON TO A CHANCE POP ALL NIGHT THOUGH ULTIMATELY THINGS MIGHT END UP DRY. SOME PATCHY FOG IS POSSIBLE...IF NOT LIKELY...AFTER MIDNIGHT MONDAY NIGHT...AND SO IT WILL BE INCLUDED IN THE FORECAST. EXTENDED (TUESDAY THROUGH NEXT WEEKEND)... THE SFC FRONT QUICKLY EITHER RETREATS OR WASHES OUT ON TUESDAY. THE END RESULT IS THE SAME...AS SOUTHWESTERLY WINDS IN THE LOW-LEVELS BEGIN TO PUMP A HOT AND HUMID AIRMASS INTO THE AREA. THIS WILL CONTINUE THROUGH WEDNESDAY. WE WILL BE VERY CLOSE TO HEAT ADVISORY CRITERIA...ESPECIALLY WEST OF I-65...BOTH DAYS. ALTHOUGH A ROGUE SHRA/TSRA CANNOT BE RULED OUT TUESDAY OR WEDNESDAY...WILL LEAVE BOTH DAYS DRY AT THIS TIME. SHOULD SEE PATCHY FOG AGAIN TUESDAY NIGHT IN THE SOUPY AIRMASS. AFTER A BRIEF PERIOD OF UPPER RIDGING NOSING INTO THE AREA...THE TROUGH PATTERN RESUMES STARTING WEDNESDAY NIGHT WITH THE MODELS DROPPING A FRONT TOWARD THE AREA AND POTENTIAL MCS DEVELOPMENT EVEN FURTHER SOUTH/EAST OF THAT. WILL ADD POPS TO WEDNESDAY NIGHT... HIGHEST IN TN...WITH JUST A SLIGHT CHANCE SOUTH OF THE TENNESSEE VALLEY DIVIDE. WILL KEEP DECENT RAIN CHANCES AROUND AS THE NEXT SFC FRONT JUST SLOWLY MOVES THROUGH THE AREA THURSDAY THROUGH FRIDAY...AND PERHAPS EVEN FRIDAY NIGHT. STILL SOME TIMING UNCERTAINTIES THERE. EVENTUALLY THOUGH...THE DEVELOPING TROUGH PATTERN WILL GET THE FRONT THROUGH... LEAVING WHAT CURRENTLY LOOKS LIKE A REALLY NICE WEEKEND...WITH TEMPERATURES BELOW NORMAL AND DRY CONDITIONS. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. && DISCUSSION...JE/23 AVIATION...SL.77
